My recommendation remains the same if this is your goal: tie both “Peak Luminance”/video_hdr_max_nits and “Paper White Luminance”/video_hdr_paper_white_nits to a single shared setting with a default of 80, 100, or 200.
Currently, the inverse tonemapper for SDR remains active, and, with a fresh retroarch.cfg, the now hidden “Peak Luminance”/video_hdr_max_nits setting is being defaulted to 1000 nits, which is an absolutely nuclear peak white brightness level for SDR.
Amusing and probably very low priority bug: when the menu is active, this setting also controls the brightness of SDR shaders.

The post you deleted seemed fine enough.
Wow! This is serious.
Is this on the Panasonic Z95B or the LG G5 or another Tandem RGB WOLED with RBWG subpixel layout?
If yes, can you post some close up photos of some grey or white content showing the subpixel layout of the screen using different Sony Megatron Colour Video Monitor TVL settings in Mask Accurate Mode please as done here:
Thanks for reporting this. Just fixed it, Vulkan was reusing the constant buffer and so had the last value written to it for the game which was the menu nits value.
Using the current Version 2 preset for the 27…40? Aperture Grille, RWGB, couldn’t find a Mask Accurate Mode setting.
300 TVL:
600 TVL:
I can never get Megatron to look good:
My HDR Guest Advanced preset with Mask Strength set to 0.90:
Just to say chaps (@PU786) the save slot thing has nothing to do with me (at least its very unlikely). You need to raise it on github as an issue so that someone closer to that system can fix it.
Have a play around with the colour spaces see if it makes any difference to you (under Your Display Settings in the shader parameters)
This picture was taken on Super, and was the best I could get the Megatron parameters set to 600 TVL. I’ve read that you don’t really support WOLED’s, and the Z95B is certainly that, so there’s probably something about the panel preventing the full use of Megatron’s capabilities.
And that’s okay, this is why we have so many different shader options to choose from. Your work is still of great value and the ways you’ve improved HDR in retroarch shine with the other HDR presets I’ve made.
So Super isnt a Colour Space option on the Sony Megatron: its either r709,sRGB,P3,Adobe or r2020. If the main menu is affecting the colour then… Ah I know whats happening youve got Guest Advanced using Super via the menu and because the Sony Megatron ignores that setting and uses its own colour spaces its using what us equivalent to Accurate which is much more desaturated. So as I say go into the Sony Megatron’s parameter settings and change Colour Space to r2020. That should make things the same as Guest.
Thank you very much.
Slow down a bit there guys. @MajorPainTheCactus, @PU786 is not reporting an issue with colour spaces or anything like that.
He’s reporting something to me, just as @Azurfel did not too long ago because I wanted to refresh and document my knowledge on the capabilities and limitations of the WOLED RWBG subpixel layout.
@PU786, ever since I learned that the new tandem RGB OLED TVs used a different, updated BWRG subpixel layout, I have wanted someone to verify and assist in getting proper subpixel shader support for them.
Due to this, I always recommended the G4 as the best OLED TV for CRT Shader emulation and the G5 with this huge caveat of it possibly needing an update to CRT-Shader Support to look as well as it could.
So now that we actually have a willing participant in you, @PU786, can you confirm how the same close up shots look with the other available Display’s Subpixel Layout, i.e. RGB and BGR? It’s no surprise that RWBG/WOLED doesn’t look or work as intended on your TV as that was designed for previous WOLED TVs, which use a different RWBG layout to your Z95B and the LG G5, G6 and C6H.
Once we see those results, we can know if an existing subpixel layout works fine, or if we need to add a new one with swapped/rearranged subpixel order in order to accommodate the newer model tandem RGB displays.
What Mask, Mask Size, Mask Zoom and Mask Layout are you using for the CRT-Guest-Advanced pics? Also, can you increase the Mask Strength to 1 for those please?
This is as close as I could get.
Still a ways off but, slightly better? I was noticing it says RWBG instead of RGWB…I’ve always kinda presumed that was the issue.
The pictures aren’t honestly capturing the night and day difference between brightness. One is with my calibrated settings (Guest Advanced) the other is with my panel cranked to the max brightness, which, while beyond overkill and washing out most things like movies/etc. still leaves Megatron washed out and dim.
Guest Advanced is set to Mask 11 with default zoom/mask layouts. This is with Mask Strength to 1, which doesn’t make much of a difference…
This is BGR Layout, which just narrowly lowers some specular highlights in the orange bricks:
Legit my camera is hiding differences/adding differences that aren’t here. Like the difference in Sonic’s blue from the Mask Strength change, and not quite capturing the difference in the orange blocks. Not super important stuff.
I’m not really interested in the full screen shots.
Take a look at the post I shared that @Azurfel made for an example of the ideal format. You can use the older Sony Megatron v1 Presets if you wish, since they definitely have a Colour Accurate/Mask Accurate shader parameter but v2 is supposed to be always Mask Accurate so it should be fine as well.
Please don’t confuse what I’m trying to do here with anything colourspace related. We just want to focus on the subpixel layouts with the aim of getting possible support for the new layout in the future.
That Mask 11 if I recall correctly is a B&W mask so it’s subpixel agnostic. There are no R,G or B, Phosphors to be found there.
Update: here is an updated CRT-Guest-Advanced Mask and Layout list:
If you want to post relevant comparisons using CRT-Guest-Adanced, you have to use the R-G-B subpixel Masks, which are Mask 6 (R-G-B), Mask 10 (R-G-B-X) and Mask 12 (RR-GG-BB-X).
For camera settings, you can use Pro/Manual Mode.
ISO low enough to not overexpose the subpixels at close range, so 100 - 250 or so.
Shutter Speed matching your content refresh rate or half of it i.e. 1/60 or 30 or 1/50 1/25.
Focus Auto or Manual
WB 5000K, Auto or whatever you think looks closest to how it looks in person.
Seems like I should have asked this question in the “OLED Subpixels, How do they work?” thread.
After reviewing your screenshots, everything looks as expected. 1080p 300TVL uses the R-G-B-X subpixel layout, which would probably look great at 1440p and 4K.
1080 600TVL uses Magenta-Green.
4K 800TVL uses R-G-B/B-G-R and that is great for 1080p.
Yes this is probably expected: have you noticed that black frame insertion does a similar thing?
Its along similar lines as in to get more similar to a CRT you have to turn off most pixels or in this case sub pixels. You mentioned when using Guest you’re using a soft mask - as in this will be switching on sub pixels that wouldnt be switched on if you are to accurately simulate the phosphor triad using the OLEDs sub pixels i.e an RGBX mask.
Take pure white, here’s its sub pixel pattern for a RGBX mask: (1.0, 0.0, 0.0),(0.0,1.0,0.0),(0.0,0.0,1.0),(0.0,0.0,0.0). Out of 12 sub pixels only 3 are on: a 75% reduction in brightness, then add in the vertical scanline simulation i e dim towards the outside and bright in the middle and its even more:say 90% reduction in brightness. So softening the mask has a huge impact on brightness at the expense of simulating a CRT less accurately: those off sub pixels in the above mask are on. This gives a ‘blurry’ look to scanlines.
This is entirely up to you what you prefer but it is to be be expected. Guest Advanced will do the same with strong pure masks no doubt.
Just as a side note these macro screenshots arent really that useful: instead try taking pictures of Sonic zoomed right in so we can see whats happening at the sub pixel level. That way I can see what is happening in Guest and what is happening in Megatron.
@PU786 Ah OK something is broken! I just tested the Megatron on Sonic and r2020 colour space is broken as in we’re not getting an equivalent colour space to Super so you’re probably still comparing Accurate (r709) to Super (r2020). Ill get this fixed ASAP so that we can get a fair comparison.
Sadly this just affected the _config versions of the Megatron but its fixed now.
Since newer WOLED monitors are getting RWBG, and apparently the G5/Z95B Tandem panels have BWRG subpixel layouts, are those going to become options in the parameters?
Apparently my panel is BWRG.
